What should I expect from 450hp?

what were your ET's in a quarter with those 355's. 1000 RPMs with small tube open headers what fuel are you running? They all sound good at an idle with open headers . Blower motor with 8-1 same thing. Show us a video of it launching on pump gas with those 355's and 9.5-1 LOL. 9.5-1 my ***

bone stock 1979 suspension, 8.25'' diff, 3.55 gears, premium 91 shell fuel. 12.05 @ 116 mph @ 3980 lbs. 1.58 60'. with the correct converter, i'm very confident i would have been 11.60's.
true measured and calculated 9.5:1 pump gas engine.
